and so as to adapt the outer journals to bear The axle box bod closelyto the sleeve, whereby said sleeve is heldimmovably in saidbody. Theouter end; of the body, E, is even with the outer end of the sleeve, D.The inner end of the body, E, has a flange,-'E1, directed toward thejournal and reaching almost to the inner cage ring, C. Diametricallyopposite each other the flange, E1, has a notch, Ela, through whichthe'sleeve, D, may be engaged for driving it out of the axle box. body.On the upper and the lower parts of the body, E, a flanged retainingplate, E2, overlaps the outer edge of said body and partially overlapsthe adjacent end of the sleeve, D, and is secured to the body, E, bymeans of a horizontal binding bolt,'E3, extending through the plate E2,into the body, E. These two retaining plates prevent the sleeve, D, frommoving outward in the body, E.

The parts above described as surrounding the journal, A2, constitute theaxle box for the journal. The axle box housing will now be described.

The housing, F, surrounds the axle box and is supported thereon. Thedrawings show the housing of U-shape cross section, the upper part beinghorizontal. The axial line of the housing is shown a little below theaxial line of the journal, A2. At its inner end the housing has a wall,Fl, extending to the axle sleeve, A7. At its front end, the housing hasan outward-directed flange, F2. In the upper part ofsaid flange is adowel socket, F3, extending horizontally through the outer face of saidflange. An outer end wall, F4, extends across the outer end of thehousing and overlaps the flange, F2. A

.dowel, F6, extends through the wall, F4, and

into the socket, F Binding bolts, F5, extend horizontally through thewall, F4, into the flange, F2, for immovably securing said wall to thebody of the housing. On the axial line of the ournal, A2, the wall, F4,has a lubricant port, F7, which is closed by means of ascrew-threadedplug, F7d. At the lower bearing face, F9, which'is to engage the ad-.

jacent side of the axlebox. Above each face,

, surrounds andfits .hold the axle box ing in the bearings, C5.

F9, a saddle member, F10, is formed integral with the body of thehousing, this member of the journal, A2. At the forward part of thesaddle, F10, is a downward-directedabutment face, F11, which isapproximately radial to the above-mentioned transverse horizontal line.

At each side of the axle box is a shoulder, E4, meeting andapproximately conforming to the under face of the saddle member, F10. Atits forward end this shoulder has an abutting face, .E5, adapted to bearagainst the saddle abutment, F11. The housing is supported on the twoshoulders, E4, by means of the saddles, F10, resting rockably on saidshoulders. Outward movement of the axle box in the housing is limited bythe abutment, F11. The curvature of the saddles,

F 10, and the shoulders, E4, allows rocking of the housing on the axlebox. The faces,

F9, on the'housing permit such rocking but ment. v

When the axle, A, and the journal, A2, and the sleeve, B1, turn, contactbetween the sleeve, B1, and the rollers, C3, causes turning of saidrollers, their journals, C4, turn-' Thus the entire roller cage turnsaround the sleeve, B1. Lubricant introduced through the port, F7, mayaccumulate in the lower partof. the housing and rise almost to theheight of the flange, F1, below the axle. Thus the lower part of'theroller cage will extend into the lubricant, all the rollers, whiletraversing their orbit, successively extending into the against sidewisemovelubricant and carrying lubricant upward to a reach the sleeve, B1,and the bearings, C5,

of the roller journals, C4.

The upper wall. of the housing is approximately horizontal. On said wallaretwo ribs, F13, in planes to which the journal axis" is perpendicular.Said ribs are spaced from each other as shown in Fig. 3. A key rib, F14,rises from said upper wall and extends from one rib, F13, to the otherperpendicularly to said ribs. At each side of the housing there are twoupright side ribs, F15, having their opposing faces in the same planesasare the opposing faces of the ribs, F13. These ribs, F13, F14 and F15,are for the purpose of obtaining seating for a saddlelike structure onthe car truck, as is already known in the railway car art.

1 I claim as my invention:

1. In a structure of the kind described, the combination with an axle,of a sleeve fitted around the axle and having threaded sockets in itsouter end, a cap having holes in alignment with said sockets, a boltextending end of the axle and screw threaded on the part extendingthrough the cap, and a nut adapted to be threaded on said bolt on eitherside of said cap, and said sockets and the holes in the cap beingadapted to receive bolts extending through said holes and threaded insaid sockets.

2; In a structure of the kind described, the

combination with an axle having a journal, of a sleeve surrounding theournal, an inner cage ring, an outer cage-ring, rollers between saidcage rings, an outer. retaining ring surrounding the outer part of thejournal and extending across the outer end of said sleeve and saidretaining ring and said sleeve being formed for inter-engagement toprevent movement of said retaining ring transversely to said sleeve, acap spaced from the outer end of the journal and bearing against theouter face of the retaining ring,

and means engaging the cap and the journal for drawing the cap towardthe journal.

3. In a structure of the kind described, the combination with an axle,of a sleeve fitted around the axle and having threaded sockets in itsouter end, a retaining ring surrounding the axle and resting against theouter end of said sleeve, a cap having holes in alignment with saidsockets, a bolt extending loosely through said cap and seated in the endof the axle and screw threaded on the part extending through the cap,and a nut adapted to be threaded on said bolt on either side of the capand said sockets and the holes in the cap being adapted to receive boltsextending through said holes and threaded in said sockets after theremoval of the retaining ring.

4. In a structure of the kind described, the combination of a journal, aroller cage and rollers surrounding the journal for travel around thejournal, an axle box surrounding the roller cage and supported on therollers, a housin surrounding and resting on the axle box body andhaving at its inner end a flange directed toward and surrounding theaxle and said housing having at its lower part a drain port and havingan outer end Wall provided with a lubricant port above the lower part ofsaid cage, whereby said housing may hold a body of lubricant reachinginto the orbital path of said rollers and said lubricant may be drainedfrom the housing.

In testimony whereof I have signed my name, this 15th day of June, inthe year one thousand nine hundred and twenty-seven.

FRANK MAXANT.
